Real time measuring system of multiple chemical parameters using microstructured optical fibers based sensors
(IEEE, 2018)
info:eu-repo/semantics/article,
In this paper, a multiplexing system for simultaneous interrogation of optical fiber sensors which measure different parameters is presented and validated. The whole system has been tested with 6 different sensing heads ...
Watt-level green random laser at 532 nm by SHG of Yb-doped fiber laser
(Optical Society of America, 2018)
info:eu-repo/semantics/article,
We have developed a Watt-level random laser at 532 nm. The laser is based on a 1064 nm random distributed ytterbium-gain assisted fiber laser seed with a 0.35 nm line-width and 900 mW polarized output power. A study for ...
Virtual FBGs using saturable absorbers for sensing with fiber lasers
(MDPI, 2018)
info:eu-repo/semantics/article,
The spectral narrowing of Fiber Bragg Gratings (FBGs) introduced by unpumped Er-doped fiber (EDF) was analyzed for fiber lasers (FL). Owing to spatial hole burning (SHB), the spectral response of a virtual FBG can be ...
Ultra-long (275 km) random distributed feedback fiber laser for remote sensor monitoring
(Optical Society of America, 2018)
info:eu-repo/semantics/conferenceObject,
An interferometric sensor located 275 km away from the monitoring station has been interrogated by a double-pumped random distributed feedback fiber laser, reaching the longest distance in fiber optic remote sensing reported ...
High sensitivity fiber-optic liquid level sensor using biconical tapered fibers
(Optical Society of America, 2018)
info:eu-repo/semantics/conferenceObject,
A liquid level sensor is presented using a biconical tapered standard single-mode fiber, being its main characteristic an outstanding sensitivity for a low cost transducer. Temperature compensation is enabled with the same ...
Gamma radiation measurements using an optical fiber laser
(Optical Society of America, 2018)
info:eu-repo/semantics/conferenceObject,
A fiber ring laser cavity configuration was used to analyze the effect of gamma-irradiation over the performance of different types of erbium doped fibers. Preliminary results validates this method to monitor gamma-radiation ...
Microstructured optical fiber sensor for soil moisture measurements
(Optical Society of America, 2018)
info:eu-repo/semantics/conferenceObject,
A discrete sensor based on a Sn0₂-FP (Fabry-Pérot) cavity is presented and characterized in real soil conditions. Results are compared, for the first time to our knowledge, with a commercial capacitive sensor and gravimetric ...
Wavelength converter using a highly Er-doped optical fiber ring laser
(IOP Publishing, 2018)
info:eu-repo/semantics/article,
This work presents an all-fiber wavelength converter based on a highly Er-doped fiber laser, which has been experimentally demonstrated. Frequencies from several kilohertz up to tens of gigahertz have been investigated. ...
